Airbag control unit with part number F01G07200H

What is the function of the airbag control unit F01G07200H?

The Bosch airbag control unit F01G07200H, also known by the Infiniti/Nissan OE number 98820JJ60A, is the central control unit for the occupant safety system (SRS) in the Infiniti G37 of the V36 series. It processes data from acceleration and crash sensors to precisely and rapidly deploy airbags and seatbelt pretensioners in the event of a collision.

As the brain of the safety system, this control unit is responsible for detecting a collision, assessing its severity, and activating the appropriate restraint devices. It continuously monitors all connected components—such as airbags, seatbelt pretensioners, seat occupancy sensors, and crash sensors—for proper functionality. Reliable operation is critical to the safety of vehicle occupants.

Technically, the device is based on a memory‑based system that utilizes an EEPROM chip (typically 95640 or 93C66). This memory stores both the vehicle configuration and, in the event of a crash, permanent crash data that locks the system.

Why does the F01G07200H fail?

The most common cause of failure for the F01G07200H is the storage of crash data after a collision. In addition, electronic malfunctions can result from voltage spikes, undervoltage, or moisture ingress. These issues lead to internal errors requiring component‑level repairs; otherwise, the unit becomes inoperable, leaving the airbags disabled.

Following a crash in which airbags or seatbelt pretensioners have deployed, the control unit writes a permanent fault entry into its internal EEPROM memory. This entry, known as “crash data stored,” permanently locks the unit and cannot be cleared using standard diagnostic tools. The system then reports faults such as “control unit defective” or specific codes like “B1000.”

Electronic failures without any crash event are also a frequent cause. Problems with onboard voltage—such as those caused by a faulty battery, jump start, or malfunctioning alternator—can damage sensitive components like voltage regulators or protection diodes on the circuit board. Water damage due to leaks in the vehicle often leads to corrosion and short circuits, especially since the control unit is typically installed near the center console.

How do you recognize a defect in the F01G07200H?

A defect in the F01G07200H airbag control unit is unmistakably indicated by the airbag or SRS warning light remaining constantly illuminated on the instrument cluster. Additionally, fault codes such as “control unit defective,” “internal error,” or “crash data stored” can be read out. In some cases, the control unit may become completely inaccessible to diagnostic equipment.

The primary and most obvious symptom is the persistently lit red airbag warning light, which fails to extinguish after engine start-up, signaling a serious, safety‑critical system fault.

During a workshop diagnosis, specific fault codes will be recorded in the fault memory. Typical entries include “crash data stored,” “control unit locked,” or general errors like “control unit defective” and “internal error.” These codes confirm that the issue lies directly within the control unit itself.

Another clear indication is when the diagnostic tool cannot establish communication with the airbag control unit, pointing to a severe internal electronic fault—possibly caused by damage to the power supply or the microcontroller.

In which models is the F01G07200H installed?

The Bosch airbag control unit with part number F01G07200H is specifically used in the Infiniti G37 of the V36 series. It corresponds to the original Infiniti and Nissan part number 98820JJ60A. At Airbag24, we repair this control unit for all variants of the Infiniti G37 V36 produced between approximately 2007 and 2016.

At Airbag24, we offer professional repair services for this control unit, which is installed in the following model:

Infiniti G37 (V36 series), manufactured circa 2007–2016

The association is clearly established through the Bosch part number F01G07200H and the OE reference 98820JJ60A. Repair ensures that the original, vehicle‑specific control unit is retained, avoiding costly modifications or reprogramming.

How is the F01G07200H repaired?

At Airbag24, the F01G07200H is repaired through professional electronic refurbishment. Upon receipt of the unit, the EEPROM memory is first read, and any stored crash data is erased. For electronic faults, defective components such as voltage regulators or driver ICs are replaced. Finally, full functionality is simulated and verified on a test bench.

After being sent to Airbag24, the control unit undergoes a standardized and thoroughly inspected repair process. First, the circuit board is visually examined for obvious damage such as corrosion or signs of burning.

The core of post-accident repair is the crash data reset. To do this, the EEPROM memory chip (type 95640/93C66) is read out, the crash records are selectively erased, and the memory is restored to its factory settings. This fully unlocks the control unit.

If an electronic fault occurs without an accident, a detailed component-level analysis is performed. Our technicians identify and replace defective parts such as voltage regulators, microcontrollers, or other ICs. Subsequently, the functionality of all sensor paths and driver stages is verified.

Following each repair, the control unit is tested on a specialized test bench. Here, we simulate vehicle sensor signals and ensure that the device communicates flawlessly and operates at full capacity. We provide 2 years' statutory liability for defects on every repair.
